It's a boy!!!
Yes, it is finally confirmed. Sunshine is in fact a male. He was missing last night and I was starting to get a bit worried but tonight he was back in his favorite burrow FLASHING! I thought his head looked a bit pale but I wasn't sure, then he chased after a mysis and I about freaked.
This means I probably have a pair. If it was 2 males they would have likely fought by this time so I have been pretty sure at least one was female.
Maybe someday he will have some eggs but even without dreaming that far in advance, it is super cool to know he is a male and is comfortable enough in his surroundings to show breeding colors.
I'll try for pics tomorrow. Lots of tank excitement here this week so the camera will definitely be in use this weekend.
